Hey guys. I'm into the sim racing as well with NR2003 by Papyrus. Actually, only been doing it for a little over a month or so, but I think I'm catching on quite well. I am in a league (OUTSIDEGROOVE) and we race on Sunday nights. And, just about every other night of the week I go on to catch some pickup races for fun and practice; however most of them of course are on the superspeedways, where our league focuses on short tracks. I like it alot, I race at our local track in the summertime, and this is a pretty darn good fix in the offseason!
I didn't mention our league runs the 88mod, and usually these pickup races I catch are in the cup mod. I know there were some great links posted, but I wanted to share a site I go to alot, which is very good and has links for pretty much anything you could possibly need for online sim racing:

And, while I'm at it, I will attempt to post a pic of the 88mod car I use for our league:
It is a copy of the paint scheme I use on my actual race car, so its quite cool to have it in a video game! I didn't do that paint job, but a very good painter from rubbins-racin.com/forum, which is a very nice online racin message board.
I recommend sim racing for anyone who is looking for a good racing fix in the offseason (or even during the season!), and has a fast enough computer, etc.
